Introduction into the rotating field theory, harmonic leakage, skewing.

Electromagnetic design of polyphase machines.

Theory of windings: design laws and calculation of winding factors for integer-slot and fractional-slot windings, imbricated windings and change-pole windings; Goerges polygon for determination of the m.m.f. curve and the harmonic leakage coefficient.

Parametric fields based on fluctuations of the magnetic harmonic conductivity of the air gap (e.g. saturation, eccentricity and slotting fields).

Current displacement in rotor cages; field damping by cage and slip-ring rotors; field damping by parallel paths of the stator winding.
